  • Patent number: 4998181
    Abstract: A system for cooling, positioning and supporting phased array microwave modules within a phased array radar system wherein the modules are disposed in cooling tubes, the cooling tubes being arranged to permit coolant to continuously pass in close proximity thereto along channels formed in a coldplate. The channels can be built into a solid member wherein the cooling tubes are hollowed out portions of the solid with channels for coolant formed in the space between cooling tubes. In alternate embodiments, the channels are formed by the spaces between cooling tubes.

  • Patent number: 4143378
    Abstract: A pendulum antenna for a microwave landing system is disclosed. The antenna is an elevation scanning antenna of the phased array type. The aperture, phase shifters, drivers and power distribution manifolds form a column-like structure. The column is suspended like a pendulum inside a fiberglass radome and windshield. The column has a degree of freedom limited by stops, damping means, and lock member. The stops set the allowable pitch angle, the damping means prevents the antenna from swinging back and forth from wind gust effects, and the lock member is used to constrain the antenna during transportation. The radome is freely mounted in a base support having adjustable legs for antenna leveling.
